METHOD OF COILING MATERIAL AND APPARATUS THENEFOR.

Application filed May 29,

The present invention relates broadly to the art of metal working, and more particularly to an improved method and apparatus for effecting the coiling of material delivered thereto.

It is customary in the metal working art to coil a wide variety of materials either for storage purposes"v or convenience in subsequent operations. While many materials are coiled with comparative ease, considerable difiiculty is experienced in the coiling of other materials, and particularly those of a softer nature such for example as copper strips or sheets.

The present invention has for one of its objects the provision of an improved method and apparatus by means of which the coiling of materials and especially materials having the characteristics referred to may he edected. V

In the accompanying drawings l have shown for purposesof illustration only. a preferred embodiment of the present invention, it being understood that the drawings do not define the limits of my invention. as changes in the construction and operation disclosed therein may he made without departing either from the spirit of my invention or the scope of my broader claims.

In the drawings:

Figure l is a diagrammatic side elevational view illustrating one embodiment of my invention, and

Figure 2 is a detail view illustrating one arrangement of coiling belts. A

In carrying out the present invention, the material 2 tobe coiled may be fed in any desired manner to a pair of feeding rolls 3. These rolls engage the material and cause the leading end thereof to engage a deflecting surface 4 which may be either stationary or trayeling. Upon engagement with the deflector, the material travels downwardly at an angle to a substantially fiat traveling surface 5 along the general path indicated by the dotted line.

When the advance end of the material on gages the substantially flat coiling surface 5, which surface may comprise a plurality of endless belts cooperating with pulleys 6 on spaced shafts 7, it is deflected laterally.

1926. Serial No. 112,630.

One or more of the shafts may be driven to cause these belts to travel in the direction indicated by the arrows. This causes the material to move to the left as viewed in Figure 1 until it engages a second traveling surface similar to the surface 5 and extending upwardly therefrom. Conveniently, the surface 8 may be formed by a plurality of belts cooperating with pulleys 9 and 10 on the shafts 7 and 11 respectively. The pulleys 6 and 9 on the shaft 7 may he alternately arranged as clearly shown in Figure 2.

The upward movement of the surface 8 deflects the material a third time, the deflection being such as to cause the material to coil upon itself, this coiling action continuing until the entire length of material is coiled. The traveling surfaces are preferably, although not necessarily, so arranged that they form substantially a right angle hetween them. I have found that such an arrangement gives very advantageous results and obviates the necessity of any mandrel during the coiling pperation. lln actual practice, however, the relative relation of these surfaces may be varied within comparatively wide limits without destroying their eflective coiling function.

If it is desired to produce a coil havin the convolutions tightly engaging eac other, it is only necessary to increase the speed of the surfaces 5 and 8 until they tend to move the material faster than the feeding means 3. This exerts a continuous pull on the material which tends to pull the coils tightly together. On the other hand, where a loose coil is desired, it may be obtained by slowing down the speed of travel of the surfaces 5 and 8 to the desired extent to elimiflecting and coiling the material.

Other advantages arise from the provision of a plurality of traveling coiling eurfaces arranged at an angle to each other, ailid preferably at approximately right an g es.

Further advantages arise from the method of changing the coil characteristics by varying the speed of travel of the coiling surfaces.

I claim:

1. In the method of coiling material, the 7 steps consisting of delivering the material to be coiled to a substantially flat traveling surface, utilizing the travel of said surface to bring the material into engagement with a second surface of similar characteristics disposed at an angle to the first. mentioned surface. and further deflecting the material by said second surface while maintaining the angle between the surfaces at all times.
